;; Semantic:
;; ---------

;;  (dir string)
;;    Path to the directory with this configuration files.
;;    Standard value is "." - the dir where dnsd was started or the
;;    directory which was passed to (dnsd-start <optional-dir>)

;;  (nameservers list-of-ip-strings)
;;    A list of nameserver-IPs used for recursive lookups.
;;    Standard value is a list of root-nameservers. 

;;  (use-axfr boolean)
;;    Toggles to answer to axfr-requests. Default value is #t.

;;  (use-cache boolean)
;;    Toggles caching of responses. Default value is #t.

;;  (cleanup-interval time-in-sec)
;;    Clean the cache and slist after X seconds. Default value is 1h.

;;  (retry-interval time-in-sec)
;;    Minimum value in seconds to trigger zone-reloads. This can override
;;    the value of some masterfiles. Default value is 1h.

;;  (use-db boolean boolean)
;;    Toggle the usage of the local database. Default value is on - #t.

;;  (use-recursion boolean)
;;    Switch the recursive-lookup on/off. Default value is on - #t.

;;  (rec-timeout time-in-sec)
;;    Global timeout for a recursive lookup. Default is 10 seconds.

;;  (socket-timeout time-in-sec)
;;    Timeout for one lookup during a recursive lookup. Default is 2 seconds.

;;  (socket-max-tries integer)
;;    Maximum nuber of tries to establish a connection for recursive lookups.
;;    Default value is 3.

;;  (max-connection integer)
;;    Maximum concurrent connections for each UDP and TCP. Default is 25.

;;  (blacklist-time time-in-sec)
;;    How long will a bad NS be blacklisted/not used? Default is 30 min.

;;  (blacklist-value integer)
;;    How often, before a bad NS will be ignored? Default is 5 times.

;;  (use-pre/post boolean)
;;    Toggles load of pre- and post-processing files. Default is off - #f.

;;  all args are optional. If not given, the def. value will be used.


;; Some examples:
;; --------------
